Interference and transposition in the speech of japanese speakers of russian

3.2. Accommodation 
Accommodation as a process is determined by a different degree of assimilation of a consonant (C) to a 
subsequent vowel (V). At the maximum of assimilation (complete assimilation is impossible), glides arise 
between the neighbouring C and V interacting in the speech flow (Loginova, 2001, p. 302). There are four 
basic accommodation positions
: CVC, C’VC, CVC’, C’VC’ (where C is any hard consonant, C’ is any soft 
consonant, V is any vowel) (Loginova, 2017, p. 194). 
The influence of vowels on preceding consonants is due to the fact that closed front vowels can cause 
palatalisation of consonants (labial, dorsal and postdorsal ones). Traditionally, it is believed that a vowel 
(especially non-front one) in the neighborhood of a soft consonant moves forward along the row and often 
becomes more closed (that is, in terms of the rise), and on the part of the soft consonant, 
[и]-shaped 
transitional section appears in the neighboring vowel, thus turning it into a diphthongoid (Loginova, 2017, p. 
194). Thus, the functioning of the hardness-softness category leads to a complex heterogeneity of Russian 
vowels in the speech flow in terms of lingual and labial articulations: all vowels are phonetically 
diphthongoidal and triphthongoidal in different positions (Loginova, 2017, p. 181). 
The phenomenon of accommodation can act in different directions and can be progressive (from a 
preceding consonant to a succeeding vowel, e.g. in Russian: 
ляг ‘lie down!’, лес ‘forest’, люк ‘hatch’), 
regressive (from a succeeding vowel to a preceding consonant, e.g. in Russian: 
дали ‘(they) gave’, о доме 
‘about home’, о луке ‘about a bow’) and two-sided, i.e. progressive-regressive (vowel mutation of under 
the influence of both preceding and subsequent consonants; this is the most prominent mutation of a vowel, 
e.g. in Russian: 
мяли ‘(they) rumpled’, о мёде ‘about honey’, о люке ‘about a hatch’) (Loginova, 2017, p. 
192). 
Consonants in Japanese are opposed according to their hardness or softness, however, the open syllable 
law regulates the degree of adjunction of a consonant to a vowel: strong adjunction in CV-sequences 
(Loginova, 2017, p. 192) (bright progressive accommodation from a consonant to a vowel, e.g.: 
hiru ‘day’, 
mise ‘store, shop’) and weak adjunction in VC-sequences (with almost no regressive accommodation, 
which also manifests itself in interference, e.g.: 
hebi ‘snake’, maki ‘roll, scroll’).
